T 0 all whom it may concern:

Be it known that T, JUmUs H. SoHLArLY, a citizen of the United Statesand resident of Canton, Stark County, Ohio have invented a new anduseful Improvement in Sheet- Cooling Machines, of which the following isa specification.

The invention relates to a machine for cooling, while carryinggalvanized sheets from the delivery table of a galvanizing pot; and theobject of the improvement is to provide means preventing a bruising ordenting of the edges of the sheets during the cooling operation.

Sheet cooling machines in common use comprise a series of wheels havingdisk hubs mounted on a shaft wih a plurality of the fingers radiatingfrom the peripheries of the disks, by the intermittent rotation of whichwheels, sheets are carried upon the fingers from one side of the machineover the hubs to the other sides thereof; and when the sheets, by reasonof their width or method of feeding, are not in contact with or adja-"cent to the peripheries of the hubs at the be ginning of the operation,they fall against the same when raised toward upright posi tion. withsuch force as to frequently bruise or dent their edges.

The present improvement involves the use of adjustable guide barsalongside the finger wheels which bars are curved to contact with theedges of the sheets as they rise upon the fingers at the beginning ofthe cooling operation, and upon which bars the sheets will slidegradually downward upon the peripheries of the hub as they approach anupright position and slide downward upon the fingers when carried overthe top of the hubs.

The inventionn may be embodied in the preferred form illustrated in theaccompanying drawings. forming part hereof. in. which- Figure 1 is aplan view of the cooling chine with parts broken away to show detaiis ofthe operating mechanism;

Fig. 2, a fragmentary elevation section on line 2-2, Fig. 1;

Fig. 3, an elevation cross section on line 3-3, Fig. 1.

Similar numerals refer to similar parts throughout the drawings.

The cooling machine comprises a shaft 1 mounted in bearings 52, onstandards 3 at the rear side of a conveyor table 4 upon which sheets aredelivered by a roller conveyor 5 leading from a galvanizing pot notshown.

The delivery table a is provided with transverse slots 6 through whichrolls 7 protrude upward for carrying a sheet longitudinally from theroller conveyor at one end to impinge the trip plate 8 at the other endof the table. The rollers '7 are continuously operated in unison by achain gear 9 driven by pulley 10 on the shaft 11, which is geared to acountershaft 12 by a pin clutch The countershaft l2 intermittentlyoperates the finger Wheel shaft 1, through a worm gear 14 whenever theclutch is actuated by the trip plate 8.

The table a is also provided with transverse slots 15 through which thefingers of the cooling wheels operate so as to receive the sheets andremove them from the table; the normal position of the wheels being withone row of fingers in substantially the plane of the table, and eachrotation of the clutch serves to rotate the cooling wheels and then stopthe same with the next row of fingers in the plane of the table, all ina well known manner.

A series of curved guide arms 16 are formed or secured on the inner endsof straight stems 17, slidably secured by bearings 18 on the undersideof the table; each arm being preferably provided with a handle 19 at its-toiuvard end for adjusting the guide bars to and from the hubs oi thecool ing wheels, and one oi the bearings is preterably provided with aclamping screw 20 for securing the guides in a given position ofadjustment.

Each guide bar is curved upward from the rear end oi its stem and thencerearward to a point preferably above the horizontal plane tangent to theupper edges of the hubs, and thence preferably downward to a pointpreferably below the said plane.

The guides are adjusted forward or rearward so that the upward curvewill be in the path of the rear edge of a sheet as it is car ried upwardby the fingers from the table, as well shown in Fig. 3; and as thecooling wheels are rotated to carry the fingers upward, the sheetsthereon contact with the guide bars and slide downward. and inward uponthe fingers after they have turned toward an upright position; and thecurve of the guide is so proportioned that as the sheets slide inwardand downward upon the fin ers their ed es will slide rearward uncn & a ai the guides and carry them gradually rearward and downward until theyride upon the hubs of the wheels, without any sudden jar or shock in sodoing; after which the sheets are carried to the rear side of the wheeland removed therefrom by manual or other means, in the usual manner.

I claim 1. sheet cooling machine including wheels having hubs withradiating fingers, and guide bars alongside the Wheels c ed upward infront of the hubs, and thence rearward toward the tops of the hubs.

2. A sheet cooling machine including wheels having hubs with radiatingfingers, and adjustable guide bars alongside the Wheels curved upward infront of the hubs, and thence rearward toward the tops oi the hubs.

3. A sheet cooling machine including wheels having hubs with radiatingfingers, and guide bars alongside the wheels curved upward in front ofthe hubs, and thence downward and rearward toward the, tops of the hubs.

at. A sheet cooling machine including wneels having hubs with radiatingfingers,

guide bars alongside the wheels curred upward in front or the hubs andthence rearwheels having hubs with radiating fingers,

guide bars alongside the wheels curved upward in front of the hubs andthence rearward toward the tops of the hubs, means for feeding sheets tothe fingers, and means actuated by the sheets forintermittentlyoperating the wheels.
